  • the fourth level debris remains in the weighing plate.
  • the screening component 2 continues to perform horizontal reciprocating motion to promote the debris to fall along the slope of the fixing plate 214 from the notch 2218 ; the cleaning water washes the debris remaining in the sieving box 22 and the collection box to the weighing plate, and then the debris flows out from the filter screen 411 of the weighing plate.
  • controller 61 issues a closing command to the inlet valve 321 , and the cleaning water stops flowing into the screening component 2 and the weighing plate to reduce the influence of water flow on the weighing process.
  • the weighing scale transmits the weighing result of the debris with the fourth level partical diameter to the controller 61 , and the controller 61 stores the weight data.

  • the above steps are repeated and the weighing of the debris of the fourth level, third level, second level and first level partical diameter is completed in turn.
  • the controller 61 calculates the distribution of the partical diameter of cuttings, and sends a closing instruction to the screening steering gears 2217 of the sieving boxes of the first, second, third and fourth levels to prepare for the next screening and weighing work.
  • a downhole failure analysis and processing method based on partical diameter distribution of cuttings includes the following steps:
  • the reference well is divided into different well sections according to formation composition and drilling process similarity. As shown in FIG. 12 , various other downhole failure monitoring methods are used to identify different types of downhole failures in each well section;
  • the representative partical diameter distribution of cuttings is selected as the standard partical diameter distribution of cuttings, and the representative partical diameter distribution of cuttings is identified as: the standard partical diameter distribution of cuttings of normal drilling and the standard partical diameter distribution of cuttings of various downhole failures; for example:
  • FIG. 13 shows the standard partical diameter distribution of cuttings selected from the normal drilling of a well section
  • FIG. 14-16 shows the standard partical diameter distribution of cuttings selected in the process of downhole failure, such as massive collapse of the well wall, general collapse of the well wall, micro-collapse of the well wall and difficulty of flowback;
  • the solution that completely removes the downhole failure will be recorded into the downhole failure treatment scheme database as a standard downhole failure treatment scheme. If the downhole failure can't be solved or the solution effect is not satisfactory, a relatively good downhole failure treatment scheme will be selected as the reference downhole failure treatment scheme and recorded into the downhole failure treatment scheme database. The reference downhole failure treatment scheme will be replaced by the downhole failure treatment scheme that successfully removes the downhole failure in the later drilling process.
  • the similarity between the real-time partical diameter distribution of cuttings and all the standard partical diameter distribution of cuttings in the same well section in the standard distribution database of partical diameter of cuttings is analyzed, and whether the real-time partical diameter distribution of cuttings is consistent with the standard partical diameter distribution of cuttings is determined according to the similarity;
  • the standard downhole failure treatment scheme corresponding to the failure should be found from the database of the failure treatment scheme immediately. After the downhole failure is resolved, continue to drill. If there is a reference failure treatment scheme in the failure treatment scheme database, the downhole failure can be treated according to the reference failure treatment scheme, or a new failure treatment scheme can be formulated according to the failure cause. When the new failure treatment scheme can completely resolve the downhole failure, the new scheme will be recorded in the failure treatment scheme database as the standard downhole failure treatment scheme. When the new failure treatment scheme cannot completely resolve the downhole failure, but the effect is better than that of the reference downhole failure treatment scheme, the original reference downhole failure treatment scheme will be replaced by the new scheme and the new scheme will be recorded in the failure treatment scheme database;
  • the method for testing the partical diameter distribution of the cuttings comprises the following steps:
  • the total weight of the sampled debris is recorded as W, and the weights of the cuttings of all partical diameters are recorded as W 1 , W 2 . . . , W k . . . , W n ;
  • the invention determines whether the real-time partical diameter distribution of cuttings is consistent with the standard partical diameter distribution of cuttings.
  • the details are as follows:
  • g k is single-level deviation
